PRODUCT PARAMETER

Note:

Data conforms to ISO 1217 (Pressure 1 bar (a), Temperature 20 deg C, R.H 0%)

Standard voltage is 380V/50HZ/3P, other voltage is available.

The recommended best capacity range is 60%-100%.

Alpine/high altitude, high temperature, high humidity, high dust loads or other adverse working conditions will require specialized custom designs. These are available on special request.

We reserve the right to make changes and improvements to the design and appearance.

Specifications may change without prior notice.
